Anyone ever closed a Classic 50 2x12 Combo back?

I've discovered is that all I really need to get the tone I want is a closed back. I can only get the C50 so close to the wall, and anyway I'd like to gig again some day, so I'm wondering about using something to change it from open to closed. It's the 2x12 combo, with the standard Blue Marvel speakers.

Disclaimer - I am NOT good with woodworking, and have no tools, so I need something simple...though I may be able to enlist the help of a neighbor that is a woodworker.

Any idea if the speakers in this would be OK with a closed back? Other things I should consider?

Thanks!

 

That's why I'm posting - in hopes that someone has done it, or knows more than I. I'd not thought about the heat, that may well be an issue....

 

The issue then is that I don't want to carry a combo and a cab if I can help it, though I may well go that route in the future....can't afford a cab at the moment.

 

See my post two posts above yours for the answer

 

Tube wear is possible - I've only had the amp since November, but it was in GC for a while so it's definitely had some play time. And yeah, tighter bass is the ONLY thing it's lacking, I absolutely adore this amp. I may replace the Blue Marvels at some point as well, though I'm not unhappy with them.

I agree, now thinking about it, that overheating would be a probability - that's why I posted before trying it, to make sure I hadn't overlooked something...which I had!
